Revealed in all of its "long-tail" glory, the new 2016 McLaren 675LT is set to become the most track-focused member of the automaker's Super Series of road-going models. Based on the recently introduced 650S and paying homage to the successful McLaren F1 GTR created for the 1997 24 Hours of Le Mans, the new 675LT's unique aero-optimized bodywork extends its nose-to-tail dimension by a barely perceptible 1.3 inches. This super coupe's enhanced wind-cheating ability is further complemented by a major improvement to its power-to-weight ratio. To accomplish that feat, McLaren trimmed some 220 pounds from the package while upping the horsepower of its bespoke 3.8-liter twin-turbo V8 from 641 to 666, a 1-2 punch that pays impressive dynamic dividends
While retaining a clear family resemblance to the 650S, McLaren says that nearly a third of the components in the new 675LT are new. The most visible changes are seen in an extended carbon fiber front splitter, deeper door-side blades and more pronounced cooling intakes. While only marginally longer, the aft section does feature redrawn fenders with integral air vents, new circular titanium exhaust outlets, a more efficient diffuser and a carbon fiber "Longtail" Airbrake that's 50-percent larger than the one on the 605S but considerably lighter
Major engine makeover
Modifications to the engine in the 675LT are even more extensive. With over half of the components new, it even merits a unique M838TL designation. Key changes include more efficient turbochargers, new camshafts and lightweight connecting rods, various detail changes to the cylinder heads and exhaust manifolds plus a faster-flowing fuel pump and optimized delivery system. Still sending power to the rear wheels via a paddle-activated 7-speed sequential shift transaxle, this more potent engine rockets the 2,712-pound 675LT from 0-62 mph in just 2.9 seconds and to 125 mph in less than eight ticks on its way to a 205 mph top end
The cabin of the new 675LT also reflects its competitive ethos, starting with a pair of Alcantara-covered carbon fiber shell-style sport buckets similar to those found in McLaren's P1 supercar. Unlike its other Super Series vehicles, McLaren has integrated the 675LT's air conditioning controls into the modestly-scaled touchscreen of its infotainment system. The 2016 McLaren 675LT is slated to arrive here sometime during the third quarter. Pricing has yet to be released, but is expected to start in the $325,000-$350,000 range
